Small batches are crushed in the Demoisy open mouthed, rubber toothed crusher and transferred to five tonne headed down open fermenters, parcels are vinified separately. Foot treading is undertaken followed by gentle basket pressing. Transferred to a mixture of oak casks to complete primary and secondary fermentation. The barrel fermented component is aged on lees for added complexity with no racking until final blending. Chester and the winemaking team undertake an extensive barrel tasting process to determine the final assemblage. High Trellis is unexposed to fining or filtration, aged up to twenty months in a combination of new and older French and American oak barriques and large casks.
